Climatologists have known for decades that airborne particles called aerosols can have a powerful impact on the climate. However, pinpointing the magnitude of the effect has proven challenging because of difficulties associated with measuring the particles on a global scale. Soon a new NASA satellite -- Glory -- should help scientists collect the data needed to provide firmer answers about the important particles. In California, engineers and technicians at Vandenberg Air Force Base are...

Shipping, China top emissions growth in new analysis of 150 years of emissions A new analysis of sulfur emissions appearing in the journal Atmospheric Chemistry and Physics shows that after declining for a decade, worldwide emissions rose again in 2000 due largely to international shipping and a growing Chinese economy. An accurate read on sulfur emissions will help researchers predict future changes in climate and determine present day effects on the atmosphere, health and the environment....

SACRAMENTO, Calif., Jan. 6, 2011 /PRNewswire-USNewswire/ -- Solar Cookers International will exhibit solar cookers from around the world that are being used to prepare food and safe drinking water. Almost three billion people still cook their daily meals over open fires using various forms of biomass -- wood, dung, charcoal and agricultural waste -- depleting the earth's rapidly vanishing forests and groundcover. Solar cooking is clean technology. It is a technology that will save the...

As the ice-capped Arctic Ocean warms, ship traffic will increase at the top of the world. And if the sea ice continues to decline, a new route connecting international trading partners may emerge -- but not without significant repercussions to climate, according to a U.S. and Canadian research team that includes a University of Delaware scientist. Growing Arctic ship traffic will bring with it air pollution that has the potential to accelerate climate change in the world's northern reaches....

Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new Stanford study.  But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice from melting. If soot emissions were eliminated, more than 1.5 million premature deaths from soot inhalation...

Dozens of scientists descended on Sacramento, Calif., in June hoping for what most of us don't want to see during hot summer days: thick, sooty haze. The team of some sixty researchers from across the country and several universities and government agencies -- including NASA scientists and aircraft -- took to the skies to sort out one of the stickiest questions in climate science: What effects do tiny aerosol particles in that haze --particularly those containing carbon -- have on the Earth's...
